Yeah. Not so much to compress for downloading, but to change the file type. I've found that browsers rarely screw with the binary data being transmitted in a zip file. Unfortunately, IE loves to screw up multimedia files for no tangible reason. It's not a major problem, but when it is a problem, it's usually pretty chronic. I can probably count on my hands the number of times I've seen this problem on my end, but zipping the source has always worked well for fixing the problem.

If you can't do that at the source, no bother though. I think I'll fire up the trusty ol' Netscape 4.7, who treats file downloads nicely almost always, even if it makes pages look like ass.

Update:
I downloaded with Netscape but still had the same problem. It's gotta be my Windows Media player, but I am totally lost on fixing it. Quicktime refuses to open it too. Alas ... t'weren't meant to be.
